Odaraia
''Odaraia'' is a genus of crustacean arthropod from the Middle Cambrian. Its fossils, which reach in length,〔 have been found in the Burgess Shale in British Columbia, Canada. 217 specimens of ''Odaraia alata'' are known from the Greater Phyllopod Bed, where they comprise 0.41% of the community. ''Odaraia'' bore a large pair of eyes at the front of its body, and may have had two smaller eyes in between. It had a tubular body with at least 45 pairs of biramous limbs, and its tail had three fins – two horizontal, one vertical – which were used to stabilise the animal as it swam on its back.〔 ==Further reading==
